Office 365 email backup solution

Hi All,

When using Office 365, how can I restore user email that was deleted few months back but hasn't been archived yet ?

If it is Exchange on Premise yes, I can always restore it from 3rd party email bckup solution, but how can I do it when is Office 365 ?

There are few thing you can try. First, they recently changed the retention policy for the Deleted items folder, now items moved there should be kept forever. So if the user simply (soft) deleted the message, check the Deleted Items folder, even if the message was deleted few months ago it might still be there.

If the message was hard deleted, *and* the user has an archive, you can check the "Recover Deleted Items" container in the *Archive* mailbox (i.e. right-click on Deleted Items in the Archive, select Recover deleted items).

If the message was Purged or the user doesnt have an archive, there's nothing you can do.

ok, what about in place hold or Journal mailbox ?

is that also possible to recover ?

My assumption is that journal mailbox is archived continuously daily real time.
It's indeed possible, but those settings need to be enabled beforehand. If you enable them now, nothing will change for messages deleted in the past.
Agree with Vasil. No 3rd party software can help you on this. Unfortunately, you've lost those emails permanently. Its time to reconfigure email retention setting so that you'll never face this loss again.
Bob,

So what's your recommendation for the retention policy ?
Set the retention to whatever you think you will need, but whatever you choose, it probably won't always cover the user that doesn't realise until 6 months later that something has gone that they desperately need.

What about setting it as forever ? is it going to work as well ?

Ah i see, so when I set the legal in place hold forever then it is archived on real time for any email send and received.

Since office 365 archiving has no limit or quota this will be the only option with no additional cost assuming E3 license is used.
